Can you please confirm my query please...

Hi All,

I am about to start full restoration of another 1971 F4.

I dont wish to keep the 845cc motor as i have an 1108cc motor sitting here in a 1983 GTL. Read on for my purpose as to why....

What i would like to know (or confirmed) is

1. The 1108 will go in the engine bay ok with a juggle of mounts

2. Can/Should i use the original early style gearbox or the 1108cc box?

3. Is there a differance in ratios between the two boxes when in 4th?

4. I also have a 1981 crash damaged Renault 5 (early model) with a good 1300cc engine in, Im guessing the 845 gearbox wont go onto the 1300 engine but will the 1108 GTL gearbox?

I would love to fit the 5 speed box but i dont want to cut out the front cross member so i would settle for the 1300 on a 4 speed box if it is straight forward.

I intend to use it to go from Cambridge to Perpignan several times a year hence my want to sit on motorways comfortably. I know the 1108 is ok for this, i just wanted to know if i could have a wee bit more power easily as i have it available?

I have just come back in a Citroen AX 1.4 Diesel and it struggled up some hills with all of my gear on board, but i did average 71.6 MPG

Many thanks, Michael

Looking forward to seeing the photos of the build!

The 1108 R4 GTL and manual 1300 Mk1 R5 engines are a straight swap with eachother (choke and accelerator cables need to be modified).

The GTL gearbox is the one to use - it has a higher ratio diff than the 850 so much easier to live with.

For changing from 850 to 1108 you'd want to swap at a minimum the engine mounts that bolt to the chassis and go to the GTL radiator position.

The bulkhead at the rear RHS needs a knock with a hammer to clear the GTL engine.

The handbrake will probably foul the fuel pump - could be blanked off and changed for an electric pump or better use the GTL suspension and brakes to get discs and a floor mounted handbrake which would better suit the 1300.

Oh i forgot about the hand break.

I will post some pictures of my projects shortly.

Thanks, michael

Good luck with the build, sounds interesting.

If, by any chance you decide not to fit the 1300 engine, I'd be rather interested in acquiring it. I think I need a faster 4.
